Add the assistant as a contact and message it in the app you already use, with no separate app to install or dashboard to learn.
Curated reply options let you move the conversation forward with less typing, so follow-up questions stay fast.
The assistant is tuned for concise responses suited to chat rather than long essays, which fits quick messaging exchanges.
Ask to explore a topic further and it can return a list of web links so you can read up on the subject outside the chat.
